。Next, the operation of the above device will be described. air supply ring 0
), the entire device except the arm @ is rotated as one by the rotating shaft (1). In the state shown in Figure 1, the air pipe (3)
The nozzle valve provided at the piston (3) closes and compressed air is not delivered to the lower chamber of the piston (3). Therefore, the piston rod (4) is pushed down by the elasticity of the spring (5), and the chi and e portions α2 of the chuck member OI are pressed against the teno groove fitting (7). Thin cylindrical parts all divided by this pressing
The diameter of the cylindrical portion formed by the tip portion is reduced by bringing the slit αJ gap closer together. In this case, when the lens to be processed (work) is placed on the core (9), the peripheral edge of the work is gripped by the reduced diameter of the thin cylindrical portion αB of the chuck member. After the workpiece is clamped in this manner, a polishing tool (not shown) such as a polisher or a sand diamond pellet is pressed against the workpiece from above, and polishing is performed while applying polishing liquid if necessary.

) and push the piston rod (4) up about 5 to 7 m. This push-up causes the chuck member 4 to rise and separate from the tapered metal fitting (7), so that the diameter of the tip of the grooved cylindrical portion (11) is expanded to its original state.In other words, the grip on the workpiece periphery is released and the workpiece is unclamped. Therefore, the workpiece can be taken out from the chuck member 4.

Unclamping can be performed without stopping. However, if an air supply path is provided in the rotating shaft (1), it is possible to omit the ring fitting on the outer peripheral portion of the cylinder.

Also, by sending compressed air through the air supply port and pushing up the piston rod, the contact between the chuck member and the tapered metal fitting is released, and the chuck member restores its diameter to stop gripping the peripheral edge of the workpiece, making it easy to unclamp. be able to. Further, by providing an air supply ring around the outer periphery of the cylinder, it is possible to easily and quickly perform a chucking operation by supplying and discharging compressed air during rotation.
